Postural orthostatic tachycardia syndrome in patients of orthostatic intolerance symptoms: an ambispective study

Postural orthostatic tachycardia syndrome

“…Nonspecific complaints can include sleep disturbances, fatigue, pain, and affective symptoms 16. Patients often have presyncope and may occasionally have neurally-mediated syncope, which includes situational syncope, carotid sinus syndrome, and neurocardiogenic syncope 17. Symptoms of POTS also often include bowel/bladder dysfunction such as diarrhea; constipation; urinary frequency, urgency, and retention; and vascular phenomena such as blood pooling in the lower extremities 16.…”

“…However, it was not formally recognized until 1993 by Dr. Ronald Schondorf and Dr. Philip Low. 1 POTS is defined in the 2015 Heart Rhythm Society (HRS) expert consensus statement as the presence of symptoms of autonomic dysfunction upon standing, which may manifest as lightheadedness, fatigue, palpitations, nausea, blurred vision and/ or tremors, with a sustained increase in heart rate of 30 beats/minute or more (40 beats/minute or more for individuals ages [12][13][14][15][16][17][18][19] within 10 minutes of standing from a supine position and without orthostatic hypotension. 1,[5][6][7] The Canadian Cardiovascular Society (CCS) position statement on POTS further delineates that while sustained orthostatic hypotension within 3 minutes of standing precludes a diagnosis of POTS, transient initial orthostatic hypotension lasting less than a minute may occur in some patients with POTS.…”

Autonomic Dysfunction Related to Postacute SARS-CoV-2 Syndrome

“…There have been case reports of NCS [ 41 , 42 ]. There may be some overlap between neurogenic syncope with POTS as NCS can occur in up to 38% of patients with POTS [ 35 , 43 , 44 , 45 ].…”

“…Current diagnostic criteria require a heart rate (HR) increment of 30 beats/min or HR >120 beats/min in the first 10 min of standing, in the absence of orthostatic hypotension, and associated with orthostatic intolerance. [ 1 ] POTS symptoms are lightheadedness, palpitations, and tremor. POTS is also associated with headaches and neck pain as the blood is not getting to the muscles and brain.…”

“…The multiple factors like moderate autonomic dysfunction, increased sympathetic tone, inadequate venous return or excessive blood venous pooling, and severe deconditioning may be responsible for POTS symptoms. [ 1 ] The mechanisms for migraine, chronic pain, and POTS symptomatology are complex and overlapped. [ 3 ] This article will help readers gain a better understanding of POTS and will assist primary care practitioners in managing it effectively.…”
